PETROLEUM-LAMP BURNER.

.SPECIFICATION forming part of Letters Patent No. 307,793, datedNovember 11, 188

Application filed August 20, 1883. (No model.)

T0 to whom, it may concern:

Be it known that I, Orro PASSOW, of Vienna, in the Empire ofAustria-Hungary, have invented certain new and useful Improvements inPetroleum-Lamp Burners, of which the following is a specification.

This invention relates tolamp-burners in which an integral cylindricalmain wick is used in connection with auxiliary suctionwicks.

In the accompanying drawings, Figure 1 represents a side elevation of myimproved burner applied to a lamp suspended from the ceiling. Fig. 2shows a vertical central section of the same. Fig. 3 represents avertical transverse section of the burner, taken on a plane at rightangles to the section shown in Fig. 2, and Fig. 4 represents a verticalcentral section of the burner applied to an ordinary lamp. Fig. 5 showsa horizontal section on line so :0, Fig. 4,- and Fig. 6 represents adetail view, on alarger scale, of the burner shown in Fig. 2.

Similar letters of reference indicate the corresponding parts.

In the drawings, A represents an interior cylindrical air-tube, which isopen at the top and bottom to facilitate the passage'of air to theflame. A wick-tube, A, is raised or lowered by means of a rack-bar, c,that is attached to the same, and engaged by a pinion, c. The shaft 0 ofthe pinion c has its bearings in the casing of the burner, and isprovided at its outer end with a toothed head, 0 At the lower part ofthe wick-tube A are arranged, at proper distance from the tube A,wick-clamps a, through which auxiliary suction-wicks a are drawn andretained thereby on the wicktube A. These suction-wicks extend into theoil-receptacle below and serve to conduct the oil to a seamlesscylindrical main wick, D, that is placed over the wick-tube A and heldat its lower end in contact with the overlapping ends of thesuctionwieks. The body of the main wick D extends above the wick-tube,and is moved by the same, together with the suctionwicks, along theguide-tube A,so as to be raised above the upper edge of the same forlighting the burner, or below the same for extinguishing it. Theintimate contact of the main and suction wicks is secured by a fixedguide-tube, 1), whereby a ready conduction of the oil to the main wickis secured. The guide-tube?) is provided at its lower part with anoutwardly-extending circumferential flange, b, which is placed against ashoulder of the threaded collar b of the oil-receptacle E, and securedthere- 'in by the exterior burnertube, A, which is screwed by itsthreaded lower end into the collar If. The exterior burner-tube, A, isbent inwardly at its upper end, the flange thus formed preventing thesuction-wicks from being raised above the upper end of the air-tube Aand burned by the flame. WVhenever a new main wick is to be inserted,the exterior burner-tube A is unscrewed and removed with the guidetube.b. A-cylindrical wick is placed over the wick-tube. The guidetube b andexterior burner-tube A' are then placed in position again, whereby thesuction-wicks are pressed against the main wick and held in contacttherewith.

My improved burner can be applied to sus= pension-lamps and ordinarylamps. In the former case air is admitted to the main wick through theinterior air-tube, A, which is pro vided at its upper end with adeflecting-disk, 6, supported on a shank, c, that is applied to thecenter of a cylindrical guide-piece, e having radial arms. The suctionwicks are in-- closed in an annular casing, B, which communicates withthe oil-receptacle E by means of openings 1; 12, arranged at the lowerpart of the outer wall of the casing 13, while the lower part of theguidetube A constitutes theinner wall.

For burners used in connection with ordinary tablevor bracket lamps theguide-tubeA is closed at its lower end, not extended below the neck ofthe oil-fount, while air is admitted to the interior of theair-tubethrough screened side openings, 9 g, which are arranged in theexterior burner-tube, and communicate with side openings 9' g g of theguide and wick tubes, as shown in Figs. 4 and 5.

The advantage of myinvention is that round burners of simple andeffective construction, with a seamless main wick,.are furnished to beused in place of the flat-wick burners. The main wick can be readilyreplaced when used up, while the suction-wicks always remain in theburner. An even and steady flame is thereby obtained, and thereby a moregeneral introduction of round wick-burners for suspension, wall, andtable lamps rendered possible.

I am aware that a lamp has heretofore been made having a stationaryair-tube and ashort wick-holder, to which a tubular wick and auxiliarywick-feeders are attached, said wick being mainly in direct contact withthe air-tube, and said wick-holder being raised or lowered by acomplicated mechanism, which action causes the wick to slide on theair-tube.

I am also aware that a lamp-burner has heretofore been made having afixed central air-tube and a tubular wick in direct contacttherewith,fed by auxiliary wicks, said tubular wick being raised andlowered on the air-tube by a spur-wheel in direct contact with the wick.

The advantages of my invention are that a more positive, regular, andeven movement of the wick is secured and the mechanism for adjusting thewick greatly simplified, this beiug accomplishedlmainly by the use of anin dependent wick-tube, to which the main and feed wicks are attachedwithout contact with the air-tube, said wick-tube being adapted to slideon the air-tube, and being provided with a rack, with whichfa pinionengages.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination, substantially as set forth, of aninterior air-tube, a wick-tube movable on said air-tube and adapted tocarry a cylindrical main wick, said wicktube being to, and also withexternal wick-clamps adapted to hold suction-wicks which overlap themain wick, and a stationary guide-tube adapted to surround thewick-tube. v

3. The combination, substantially as set forth, of an interiorair-tube,awick-tube movable on said air-tube and adapted to carry acylindrical main wick, said wick-tube being provided with externalwick-clamps adapted to hold suction-wicks which overlap the main wick, astationary guide-tube adapted to surround the wick-tube, means forraising and lowering said wick tube, and an exterior burner-tube havingan inwardly-bent guardflange at its upper end.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
